in my opinion, i dont think early persian casting surpassed that of 16thC india, which incorprated techniques still used today (in india or course). not saying indian work was better, but was easily the equal in techinique and quality, and many centuries later.
i have seen the lecture and i feel that he was promoting all things persia, using slight exaggeration. nothing wrong with this. i have a dealer friend that i share a regular joke with. each piece he shows me is ''the best in the world''. he doesnt actually mean this, he just means his piece is pretty bloody good.
so, i feel the lecturer meant that persian casting was of a high quality, which he expressed by saying it was the ''best in the world''.
just a salesmans pitch. maybe he is on commission from the iranian tourist board? (joke!!! please dont anyone get offended!!)
